VENTILATED SHOE.

Application filed June 25, 1923. SerialNo. 647,651.

To all whom. it may concern:

Be it known that I, ELMER MENEFEE, a

citizen of the United States, residing at Gilbert, in the county of Muskingum and State of Ohio, have invented certain new and useful Improvements in Ventilated Shoes, of which the following is aspecification.

This invention relates to improvements in shoes. 7 The primary object of this invention is the provision of a ventilating shoeembodying novel means of construction as a part of the shoe, whereby the shoe maybe ventilated at all times.

A further object of this invention. -is the provision of a shoe which is particularly well adapted to be worn by persons whose employment or other necessity requires that they traverse hot flooring, paving, or other surfaces, such as workers in iron and steel -mills; the structure of the improved shoe providing means to insulate the foot of the wearer from abnormal temperatures.

A further object of this invention is the provision of a novel insole structurefor A further object of this invention is the provision of novel cushioning means for footwear to absorb shock incident to travel.

Other objects and advantages of this invention will be apparent during the course of the following detailed description.

In the accompanying drawing, forming a part of this specification, and wherein similar reference characters designate 'corresponding parts throughout the several views,

Figure 1 is a longitudinal cross sectional view, taken through an improved shoe constructed after this invention.

Figure 2 is a cross sectional view, taken substantially on the line'22 of Figure 1, showing certain parts of the same broken away to expose novel features of this invention.

Figure 3 is a fragmentary plan view of the rear portion of the improved shoe.

In the drawing, wherein for the purpose of illustration is shown but the preferred embodiment of the invention,- the letter A may generally designate the improved shoe, which ma include an outer sole and heel structure upper structure F; insole H of novel construction; and means K providing other novel features of this invention.

' The outsole and heel structure B of the improved shoe A may be of any approved construction and material, and it is preferred that a marginal upstanding flange 10 be provided -about the entire outer sole and heel structure B, providing a pocket 11, so to speak, into which the upper F fits for attachment to said flange 10.

Referring to the construction of the insole H, the same is for detachable placement within the shoe A in spaced relation over Immediately over the out sole and heel.

structure B and following the contour of the flange portion 10, cushioning and spacing spring structure 20 is provided, which is preferably of good grade resilient wire. The

cushioning spring 20 maybe of a single This piece arranged longitudinally of the sole and heel structure B, wound from the margin of the same to the longitudinal center thereof, substantially as is illustrated in Figure 2 of the drawings. The spring structure 20 is attached to the sole structure B as by relatively small staples (not shown) so that the longitudinal arrangement of the same may not be displaced. The insole H is adapted to rest upon the top of the spring structure 20 to provide anair space 23 intermediate the aluminum plate portion 15 of the insole H' andthe top surface of the outsole and heel structure B. This space .23 extends from the extreme toe of the shoe A to the heel thereof. The back of' the shoe is of novel construction, including a wall 25 ordinarily provided by the upper structure F, and a' member 27 secured within the shoe A in any approved manner tdthe upper portion F. Intermediate the walls 25 and 27, vertical spiral springs 28 are arranged in any number to provide a passageway 29 open at the top margin 30 of the upper structure F, and having communication with the space23 at the rear of the shoe. The springs 20 and 28 are of suflicient inherent resiliency to support the weight of the wearer without collapsing and thus-maintaining the spaces 23 and 29 open as an insulating and ventilating passageway.

From the above description of this invention, it is apparent that a novel shoe structure has been provided, which is relatively simple in construction, in the provision of a sole insulating and ventilating space which extends entirely longitudinally and transversely of the shoe and is open at the top of the shoe through a communicating passageway at the rear of the shoe.

Various changes in the shape, size and arrangement of parts may be made to the form of invention herein shown and described, without departing from the spirit of the invention or the scope of the claim.

I claim:

A' shoe structure comprising an outsole and an upper'connected with the outsole, an

insole in said shoe and having a lower plate of perforated flexible metal and a covering for said plate having perforations registering with the perforations of the plate, a coiled spring between the outsole and metal plate of the insole and disposed in a spiral path beneath the perforations of the insole and holding the insole in spaced relation to the outsole, a strip in the rear portion of the shoe extending from the-insole to the top of the upper and having its lower end secured about the heel portion of the insole and its side portions secured to the upper, the intermediate portion being free from the upper and providing an air passage leading from the space between the insole and outsole to the upper edge of the rear portion of the upper, and coiled springs disposed vertically in the space between the last mentioned strip and rear portion of. the upper.
